Since Tuesday, 5 May, 06:30 CET, we have been experiencing technical issues caused by high demand on our systems, which have significantly affected our journal libraries. To maintain platform stability and ensure continued access to critical services, all preprint and journal article PDFs were temporarily restricted, while HTML full-text content and XML files remained available. Since Thursday, 7 May, 08:30 CET, we have made the preprint PDFs available again; however, journal article PDFs remain restricted until the technical issues have been resolved. We apologize for the inconvenience and appreciate your patience as we work to restore full PDF access as quickly as possible. Thank you for your understanding.
